See Raymond's response :)
<cfif isDefined("caller.form")>
//hmmm spotted problem...should name defaults differently
<cfif attributes.value NEQ value> <--- onChange
<cfset value = "Form submit successful and you changed the default!">
<cfelse>
<cfset value="Form submit successful!">
</cfif>
</cfif>
Could probably go really far and define onChange, onSubmit, etc.
methods for each input. I'd prefer the form collection itself to be an
object though, instead of a structure. This would all be easier if so.
